Manchester United transfer news: Five strikers who could arrive at Old Trafford in January

The Chilean forward has effectively been put up for auction by boss Arsene Wenger, who says it would be ‘beneficial’ to spark a bidding war for his contract rebel. Manchester City remain favourites to sign the 29-year-old but the Red Devils will battle their rivals until the end of the window if they believe Sanchez would entertain a move to Old Trafford. United have reportedly offered £25million for Sanchez and are likely to set the benchmark for any transfer fee that involves the departure of Sanchez from the Emirates Stadium.
